The Doctor: The time(less) lord of science The Doctor: The time(less) lord of science

The timeless Lord of Science, Dr Karl Kruszelnicki, is back.

No need for a TARDIS... jump through 'wibbly wobbly' theories of time travel, and discover how alcohol makes you speak louder, how to tell what part of a movie the audience is watching without looking, and why Americans are no longer the tallest people on Earth. What will the discovery of gravitational waves do for you? Why do you sleep badly in an unfamiliar bed? Why should you exercise before breakfast (not after) to stop weight piling on?

Stranger things: The uncanny world of animal pregnancy Stranger things: The uncanny world of animal pregnancy

Giving birth to a live baby, rather than laying an egg, is an important biological innovation allowing animals to incubate embryos internally. You might be surprised to learn that live birth (viviparity) has evolved independently hundreds of times in very diverse species, including lizards, sharks, and even cockroaches. However, we know little about pregnancy beyond mammals like ourselves, which is where Dr Camilla Whittington's research comes in.

Life in the city: Why nature persists in ubran environments Life in the city: Why nature persists in ubran environments

We often think of cities as concrete wastelands, where humans and their structures dominate and our natural systems are lost. The reality is that a surprising number of animals and plants manage to persist in cities. Some even thrive, seemingly better off in our modern cities than in their natural habitats.

Does stress cause cancer? Does stress cause cancer?

You may wonder whether stress can increase your risk of cancer: can stressful life events, such as divorce or conflict at work, result in a serious illness like cancer?

A number of studies have investigated this question, with mixed results. Some very large studies, which have followed thousands of people over time, have found that stress does increase risk of cancer, while other similar studies have not. In reality, it is likely that a mix of factors influence risk. Professor Phyllis Butow will reveal the findings from a new Australian study, which involved more than 2000 women, and examined the link between stress and cancer.

Nature's Engineers Nature's Engineers: How ants, bees and slime moulds are helping us build better cities

Can ants build better infrastructure networks than us? Despite having tiny brains, ants build efficient transportation systems, manage complex supply chains, and have effective communication networks. Even brainless slime mould amoebas can design transportation networks that are as efficient as those built by human engineers. Like human designed infrastructure systems, natural systems must stand up to a slew of disruptions from targeted attacks, to traffic jams, to natural disasters. Unlike human designs, natural infrastructure systems have had millions of years to evolve solutions.

Dr Karl's Short Back and Science 2084: How future medicine will create a happier world

Albert is born on 5 June 2084. At birth a prick of blood is drawn for DNA sequencing of his genome and epigenome. The Wellness App diagnoses Albert’s long term disease risks. Fecal matching is done and he is given an optimal colonisation from a suitable donor.

For the first two years of Albert’s life he is provided with careful environmental cues matching his DNA profile, ensuring optimal neuronal synapses in the brain for a happy and healthy life. The MedChip is implanted at six months to monitor sleep, food, activity and language. Data is uploaded to the Wellness App providing Albert with constant feedback about his optimal life options.

Unlike the Orwellian view of life, now we have learned how to help people live happier healthier lives. This requires individuals to take control of their own data and their own health for better outcomes. Discover how metabolic systems biology could revolutionise our health by offering precision medicine.

Dr Karl's Short Back and Science Dr Karl's Short Back and Science

In Short Back & Science, Dr Karl probes the link between earwax and armpit sweat (and why polyester shirts stink), and why we draw stars as having points (even though stars are enormous spherical blobs without points). Also find out how radioactive you are, how much clouds weigh and whether cows can really make strawberry milk.

Dr Karl will also look at the Galapagos Islands, as well as what happens when you go looking for Auroras in a sailing boat in the Arctic Ocean and get hit by a major weather depression – and why vomiting (and fear, for that matter) are both contagious. And how did a 25-year-old Australian Physics Nobel Prize winner help change the course of World War I (as a result of being lifted off the toilet seat, whenever the Big Guns fired)?

Short Back and Science – science has never looked better!

The Quantum Future: Powering the next technological revolution The Quantum Future

Whether you know it or not, quantum mechanics powers almost every piece of technology you encounter day-to-day: from LED lights in your home to the microprocessor in your mobile phone. Despite the ubiquity of these technologies, they represent only the first step of what is possible if we harness the full breadth of what quantum mechanics has to offer, including a suite of counterintuitive properties that we often call ‘quantum strangeness’.

Time After Time: Measuring Evolution with Molecular Clocks Time After Time: Measuring Evolution with Molecular Clocks

Fossils have allowed us to work out when animals first evolved, when plants colonised land, and when we shared ancestors with our primate cousins. But what if we are interested in the history of organisms that are not preserved in the fossil record? We can use molecular clocks to estimate these evolutionary rates and timescales from genome data.

Nemesis: the search for antimatter in the universe It's the ultimate battle of the universe: when normal matter and antimatter come together, they're annihilated, and all the mass is converted into energy. Fortunately, the Universe today is composed almost entirely of matter, with very little antimatter. However, the laws of physics require that the Universe began with equal amounts of both. The origin of the asymmetry is not known, but a possible explanation relies on some bizarre events in the early Universe.
